Pet waste scoop assembly

ABSTRACT

A pet scoop assembly and method of use is provided. The assembly includes a scoop member; a receptacle detachably engageable with the scoop member; and a door disposed intermediate the two. A disposable bag may line the receptacle and be clamped in place between the receptacle and scoop member. The door opens inwardly into the receptacle. When the scoop assembly is turned into a vertical orientation, the door opens by gravity or by the weight of gathered pet waste sliding onto the door. A region of the scoop member adjacent the door is angled to allow pet waste to slide readily from the scoop member into the receptacle.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a Continuation of U.S. patent application Ser. No.14/519,239, filed Oct. 21, 2014 which claims the benefit of U.S.Provisional Patent Application Ser. No. 61/916,493 filed Dec. 16, 2013,the entire specification of which are incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Technical Field

This invention relates generally to pet supplies. More particularly thisinvention relates to pet waste scoops. Specifically, the invention isdirected to a scoop assembly for removing clumped waste material frompet litter boxes or from surfaces such as grass; which scoop assemblyincludes a detachably engageable scoop member and receptacle separatedfrom each other by a movable door; where the door opens to permit petwaste to slide into the receptacle and closes afterward to secure thewaste in the receptacle.

2. Background Information

Ever since humans domesticated dogs and cats and welcomed them intotheir homes, disposing of their waste products has been an issue. Thisissue has grown exponentially as more people now live in urbanenvironments than ever before. In many instances pets, particularly catsare kept indoors at all times and the pets therefore have to utilizelitter boxes. Litter boxes are typically filled with specially designedlitter materials that form clumps around urine and feces. These litterboxes need to be cleared of pet waste on a regular basis in order toprevent unpleasant odors from overtaking the home. It is only needfulfor the homeowner to remove these pet waste clumps from the litter boxto keep the home odor free and so that the cat will continue to use thelitter box rather than go elsewhere in the house.

In the case of dogs, many pet owners will either release their animalsinto a yard to relieve themselves or, if a yard is not available, theywill take their dogs on walks for the same purpose. Thus, instead ofeliminating in a litter box, dogs may eliminate on grass, or sand oreven concrete. This pet waste also has to be cleaned up.

Since it is undesirable to directly handle the pet waste clumps inlifter boxes or the pet waste in grass or on other surfaces, a varietyof pet letter scoops have been developed. For example, U.S. Pat. No.5,580,111 (Bohn) discloses a scoop for animal waste. The scoop defines aplurality of apertures in a bottom wall thereof and through whichunsoiled pet litter will drop back into a litter box. Alternatively, thebottom wall may be formed into a plurality of tines or fingers which areseparated from each other by apertures. A collection container (i.e., abag) is engageable with one end of a funnel on the scoop. The scoop ismoved into a substantially vertical position to cause captured waste toslide down the funnel and into the bag. The weight of the pet wastecauses the bag to hang downwardly from the scoop and may interfere withlifting additional pet waste from a litter box. A tongue is thereforeprovided on the scoop to cause the bag to be held a distance away fromthe scoop end of the device. Once all the waste is removed from thelitter box, the bag is detached from the scoop and is disposed of. Oneof the problems with this device is that the user has to hold the funnelportion of the device with one hand and hold the bag in engagement withthe funnel portion with the other hand when the device is being used. Ifthe user's second hand slips during the motion where the scoop is movedto the vertical, the bag could separate from the funnel causing thewaste to miss the bag and drop onto some other surface.

U.S. Pat. No. 7,686,360 (Platt) discloses a device comprising a scoopwhich has a funnel integrally formed therewith and extending outwardlyfrom one end thereof. A bag may be pulled up around a free end of thefunnel and is locked into place by way of clips provided on the exteriorsurface of the funnel. An upstanding wall is provided between the bottomwall of the scoop portion of the device and the bottom wall of thefunnel portion of the device. The upstanding wall is provided to preventalready-gathered pet waste from sliding from the funnel back down thescoop when the scoop is used to pick up additional pet waste. The funnelis moved to a vertical position to cause the pet waste to slide throughthe funnel and into the bag. When the litter box is cleaned, the bag isdetached from the funnel and is thrown away. One of the problems withthis device is the presence of the horizontal wall. The scoop includes agently sloped back region (adjacent the funnel) which is supposedlythere to help captured pet waste to slide into the funnel. In order tomove the waste from the scoop to the funnel, the device is moved to anorientation where the funnel is generally vertical. However, it isnecessary for the waste to get past the now horizontally-oriented wallas it will have a tendency to just sit there on the wall. So, it isnecessary for the user to give the device a little shake to dislodge thewaste so that it will drop into the funnel. This, of course, couldresult in the waste flying completely out of the device if the “littleshake” is too vigorous.

GB 2243535 (Lowrie) discloses a device having a housing that is shapedto be able to be used as a scoop. The housing defines a cavity thereinand a bag is received within this cavity and is positioned so that itoverlaps the rim of the housing. A rotatable barrel is received withinthe housing and at least a base portion thereof is accessible outside abottom end of the housing and the bag extends into the barrel. A door ismounted at the forward-most end of the housing and is movable between anopen position and a closed position. The door includes a protuberancewhich is engaged by a person's thumb to cause the door to pivotoutwardly away from the housing and into an open position so that thehousing can be used as a scoop. When the person lifts their thumb offthe protuberance, the door will rotate back toward the housing,returning to the closed position. This device is suitable for picking uppet waste that is laying on grass or a sidewalk for instance, but is notsuitable for sifting animal waste from a litter box as there is no wayfor clean litter (i.e. litter free of clumps containing pet waste) to bereturned from the housing to the litter box. The device also has anotherproblem in that it really is only suitable for one attempt at picking upthe pet waste. This is because there will be a tendency for capturedwaste to slide back out of the housing when the housing is tipped intothe appropriate position for scooping up waste. This tendency isenhanced by the gently angled front wall that is used as the scoop.

Melitta Zentralgesellschaft mbH & Co. KG, a German corporation,operating under the trade name Swirl® discloses on its website a scoopfor a litter box that includes a scoop portion and a receptacle portion.The scoop portion includes a handle and a grate. The scoop is used toremove pet waste from a litter box and the grate permits clean litter tobe returned to the box while capturing the waste on the grate. Thedevice is turned to a generally vertical orientation to drop capturedwaste into the receptacle. One of the issues with this device is that ifit takes several scoops to remove all the pet waste from the litter box,each time the scoop is tipped to introduce its leading edge into thelitter, there is a tendency for already captured waste to slide out ofthe receptacle, back down the scoop and back into the litter box. Whenit is desired to remove the waste from the device, the receptacle isdetached from the scoop and is tipped upside-down to drop the capturedwaste into the garbage. It is not really necessary to detach thereceptacle from the scoop in order to do this because the entire devicecan be tipped upside down to cause the captured waste to slide out ofthe receptacle. A further issue with this product is that the scoop isrounded at the front, making it quite difficult to remove waste from allregions of litter boxes as the boxes tend to be generally rectangular inshape, having vertical exterior walls and right-angled corners.Additionally, the scoop has generally non-existent side walls which willpermit waste on the grate to drop back into the litter box. This systemalso does not easily accommodate a bag since the scoop twists onto thecontainer like a bottle top that could rip or tear the bag during use.

SUMMARY

While all of these aforementioned devices function reasonably well forthe purposes for which they were intended, there is still a need in theart for an improved pet waste scoop that addresses some of theshortcomings identified above. The pet scoop assembly disclosed hereindoes exactly that.

The disclosed pet scoop assembly includes a scoop member; a receptacledetachably engageable with the scoop member; and a door disposedintermediate the two. A disposable bag may line the receptacle and beheld in place between the receptacle and scoop member. The door ispositioned to open inwardly into the receptacle. When the scoop assemblyis turned into a vertical orientation the door opens by gravity or bythe weight of gathered pet waste sliding onto the door. A region of thescoop member adjacent the door is angled to allow pet waste to slidereadily from the scoop member into the receptacle. In a variation, thescoop member is provided with a plurality of tines that enable pet wasteto be removed from surfaces such as grass. An elongate handle isprovided on this scoop to allow the user to stand upright during use.

DETAILED DESCRIPTION

Referring to FIGS. 1-9, there is shown a pet scoop assembly, generallyindicated at 10. Scoop assembly 10 includes a scoop member 12 and areceptacle 14 which are selectively engageable with each other. Assembly10 further includes a handle 16.

Handle 16 extends upwardly and outwardly from scoop 12. Handle 16 isthus illustrated as forming part of scoop member 12 but it will beunderstood that handle 16 may, instead, form part of receptacle 14 or beprovided on a separate frame member that may be disposed between scoopmember 12 and receptacle 14. Additionally, handle 16 is shown as beingan integral part of scoop member 12 but it will be understood thathandle 16 may, instead, be a separate component that is selectivelydetachably engaged with scoop member 12. Similarly, if handle 16 is partof receptacle 14 or a separate frame member disposed between scoop 12and receptacle 14, then handle 16 may be detachably engageable with theassociated one of the receptacle or the separate frame member.Furthermore, handle 16 may itself be a single unitary component orhandle 16 may be comprised of two or more individual components that aresecured together in a suitable manner to form the handle. Additionally,the underside of handle 16, i.e., the surface of handle 16 disposedadjacent receptacle 14 may be provided with some type of grippingsurface or texturing to aid a user in holding on to handle 16. Handle 16is further ergonomically designed so that the handle is at a comfortableangle for a user to hold and manipulate and so that handle 16 is easy togrip. It should be understood that the exact configuration of handle 16is not limited to the specific design shown in the attached figures butany ergonomically shaped handle that is disposed spaced apart from andgenerally parallel to a first wall 14 a of receptacle 14 is mostdesirable. Handle 16 may include a thumb rest 16 a for seating of auser's thumb therein during operation of scoop assembly 10.

Scoop member 12 includes a frame 18 which may be generally rectangularin cross-section, although other shapes are possible. Frame 18 of scoopmember 12 detachably engages an upper end of receptacle 14. Frame 18includes a first wall 18 a; a second wall 18 b, a third wall 18 c, afourth wall 18 d, and a fifth wall 18 e. All of the walls 18 a-18 e areintegrally formed with each other to form a unitary member. Walls 18a-18 e bound and define an opening 20, the purpose of which will befurther described herein. One or more apertures 22 are defined in atleast each of first wall 18 a and second wall 18 b. Apertures 22 mayadditionally or alternatively be defined in third and fourth walls 18 c,18 d. Apertures 22 are provided for interlocking engagement withcomplementary protrusions 34 on receptacle 14, as will be laterdescribed herein. It will be understood that instead of apertures 22being defined in first and second walls 18 a, 18 b, depressions could beformed therein to interlockingly engage protrusions 34 on receptacle 14.Still further, the protrusions 34 could be provided on scoop member 12and the associated and complementary apertures 22 or depressions couldbe defined in receptacle 14, or a combination of complementaryreceptacles and protrusions could be provided on each of scoop member 12and receptacle 14.

While frame 18 is illustrated and described herein as forming anintegral part of scoop member 12, it should be understood that frame 18may, alternatively form part of receptacle 14. Still further, asdiscussed earlier herein, frame 18 may comprise an independent framemember that is an independent component positioned between scoop member12 and receptacle 14 and be detachably engaged with each of scoop member12 and receptacle 14. In this latter instance, frame 18 could releasablybe engaged with scoop member 12 in much the same manner as it currentlyillustrated and described as being releasably engaged with receptacle14.

Scoop member 12 includes a front region which extends outwardly andforwardly from frame 18. This front region includes a bottom wall andside walls. Bottom wall, which includes a first section 12 b, a secondsection 12 a and a third section 12 a′, extends forwardly from fifthwall 18 e of frame 18. (Third section 12 a′ may be provided with one ormore holes 27 which may be utilized to suspend scoop assembly 10 from ahook mounted on a wall.) Side walls 12 c, 12 d extend forwardly fromsections 18 c and 18 d of frame and further extend upwardly andoutwardly away from the outer edges of third, second and first sections12 a′, 12 a, 12 b of the bottom wall and generally at right anglesthereto. It will be understood that while side walls 12 c, 12 d areillustrated herein as being disposed generally at right angles to thebottom wall sections 12 a′, 12 a, 12 b, they may also flare slightlyoutwardly away from bottom wall when scoop member 12 is viewed from afront end.

Scoop member 12 includes an outer rim 25. Third section 12 a′ of thebottom wall originates at rim 25 and extends for a distance inwardlytherefrom. Rim 25 has an angled profile (FIG. 4) to make it suitable forscraping. Rim 25 is also stiffened or hardened so that it is not easilydamaged during use and so that it is strong enough to move readily andeasily through litter material 46 (FIG. 10) in a litter box 48. Rim 25needs to be sufficiently rigid and strong enough to scrape wastematerial 47 off the bottom or sides of litter box 48 or to travel acrosssurfaces such as grass or cement. Second section 12 a of the bottom walloriginates at a rearward region of third section 12 a′ and extendsinwardly to a forwardmost region of first section 12 b. First section 12b terminates proximate wall 18 e of frame 18. Second and first sections12 a, 12 b are disposed at a first angle of from about 130° up to about135° relative to each other. This first angle is represented by thereference character a in FIG. 4. Third section 12 a′ is disposed at asecond angle β relative to second section 12 a, and angle β is fromabout 150° up to about 160°. Furthermore, when scoop member 12 andreceptacle 14 are engaged with each other, second section 12 a isdisposed at an angle of from about 145° up to about 160° relative to thesecond wall 14 b of receptacle 14; and first section 12 b is disposed atan angle of from about 25° up to about 35° relative to second wall 14 bof receptacle 14. The corners 12 e of scoop member 12 are gently curved.These curved corners 12 e help scoop assembly 10 reach into corners oflitter box 48, as will be later described herein. The bottom wall 12 a′,12 a, 12 b and side walls 12 c, 12 d may be integrally formed with frame18.

The configuration of the bottom wall of scoop member 12 is such thatlitter material 46 with clumped pet waste 47 therein is scooped ontothird section 12 a′. The litter material 46 and clumped pet waste 47slides down third section 12 a′ and onto second section 12 a. Littermaterial 46 and pet waste 47 will tend to become initially retained inthe V-shaped region between second and first sections 12 a, 12 b. Whenscoop assembly 10 is moved from a horizontal orientation (FIG. 4) towarda vertical orientation (FIG. 13), as will be later described herein, theclumped pet waste 47 slides onto first section 12 b. The angle of firstsection 12 b is such that when the entire scoop assembly 10 is furthermoved into a vertical orientation, the pet waste 47 will tend to slidedown the surface of first section 12 b toward opening 20 andsubsequently into receptacle 14. This will be described in greaterdetail later herein.

Bottom wall sections 12 a′, 12 a, 12 b of scoop 12 includes a pluralityof tines 23 which are separated from each other by a plurality ofapertures 24. Apertures 24 are provided so that un-clumped anduncontaminated pet litter is able to be separated from clumped andcontaminated pet litter and be subsequently dropped through apertures 24and back into a litter box, as will be hereinafter described. Side walls12 c, 12 d are also provided with a plurality of apertures 24 for asimilar reason, although it will be understood that side walls 12 c, 12d may be free of such apertures 24. Any desired pattern of apertures 24and tines 23 may be utilized in bottom wall sections 12 a′, 12 a, 12 band side walls 12 c, 12 d to provide a grate-like surface which willcapture larger materials and allow smaller materials to passtherethrough.

Referring to FIG. 4A, each tine 23 includes an upper surface 23 a, alower surface 23 b, first side surfaces 23 c, and second side surfaces23 d. First side surfaces 23 c are oriented opposite and generallyparallel to each other. Second side surfaces are oriented opposite eachother and at an angle relative to each other. Each tine 23 tapers froman end region of first side surfaces 23 c to the lower surface 23 b.Rounded corners 23 e are provided between upper surface 23 a and each ofthe first and second side surfaces 23 c, 23 d. The radius of curvatureof corners 23 e may be around 0.25 mm. First side surfaces 23 c angledownwardly from the associated corner 23 e and connect to second sidesurfaces 23 d which then each connect to lower surface 23 b at a corner23 f. Each of the first side surfaces 23 c originates about 0.5 mmdownwardly from upper surface 23 a. Each second side surface 23 d may beat an angle of about 165° relative to lower surface 23 b. Overall, tine23 tapers from upper surface 23 a to the lower surface 23 b. Thisconfiguration of tine 23 has been found to work well for removingclumped litter material from litter boxes 48. The apertures 24 permitunclumped litter material 46 to fall back into litter box 48. Littermaterial that clumps around feces does not tend to break apart whenscoop assembly 10 is shaken in order to cause un-clumped litter material46 to drop through apertures 24 and back into litter box 48. However,litter material that clumps around urine tends to form clumps that arequite fragile and tend to break apart relatively easily. Thecross-sectional shape of tine 23 (shown in FIG. 4A) has been found to besuitable to help maintain the integrity of these fragile clumps and willat least somewhat reduce the tendency of the clumps to break apart andfall back into the litter box 48. If broken-apart clumped littermaterial is returned to litter box 48, cats will tend to avoid using thelitter box because of the smell emanating from the small particles oflitter material containing urine and/or feces. Utilizing the shape oftine 23 shown in FIG. 4A will therefore aid in prolonging the time thatlitter material can be used. It will, of course, be understood thattines having a different cross-sectional shape may be used in the scoopassembly 10 instead of the tines 23 illustrated herein.

Receptacle 14 is shown in greater detail in FIGS. 2 and 3. Receptacle 14includes a peripheral wall comprised of a first wall 14 a, a second wall14 b, a third wall 14 c, and a fourth wall 14 d. This peripheral wallextends outwardly away from a fifth wall 14 e. First wall 14 a may bereferred to herein as the upper wall and second wall 14 b may bereferred to as the lower wall of receptacle 14. This is because secondwall 14 b will be adjacent to a surface upon which pet waste 47 restswhen scoop assembly 10 is oriented in a horizontal position in order tolift that pet waste from the surface. A plurality of feet 13 is providedon fifth wall 14 e. Feet 13 will support receptacle 14 a short distanceabove a surface 19 when receptacle 14 is moved to a vertical orientation(FIG. 15) and is placed on surface 19.

Receptacle 14 may be a rectangular cube in shape, although any otherdesired shape could be utilized provided that receptacle 14 and scoopmember 12 are complementary so they may be engaged together. Peripheralwall 14 a-14 d and fifth or bottom wall 14 e bound and define a cavity32 (FIG. 2). The outer edges of walls 14 a-14 d remote from fifth wall14 e bound and define an opening to cavity 32. A region of each wall 14a-14 d inward of the outer edge is recessed so as to form a lip 14 f.Lip 14 f is provided at the outer end of receptacle 14 and is shaped andsized to be complementary to and detachably engageable with walls 18a-18 d of frame 18.

As previously described, scoop assembly 10 includes some type of lockingor latching mechanism for detachably securing scoop member 12 andreceptacle 14 together. As illustrated in FIG. 5, one suitable lockingor latching mechanism comprises one or more protrusions 34 provided onthe exterior surface of lip 14 f and mating apertures 22 defined inframe 18. Protrusions may be integrally molded with receptacle 14 andare not movable relative thereto. (It will be understood thatprotrusions 34 may, instead, be provided on scoop member 12 andapertures 22 defined in receptacle 14.) Protrusions 34 are selectivelyreceivable in the apertures 22 on frame 18 to retain receptacle 14 andscoop member 12 together. Additionally a ridge 15 (FIG. 5) extendsoutwardly from the exterior surface of walls 14 a, 14 b, 14 c, and 14 dof receptacle 14. Ridge 15 abuts the outermost edge of scoop member 12and acts as a stop, thereby limiting the inward travel of scoop member12 when scoop member 12 and receptacle are engaged with each other.

Scoop assembly 10 further includes a door 26 which separates scoopmember 12 from receptacle 14. Door 26 may be provided on scoop member 12as shown herein but may, alternatively, be provided on receptacle 14 ina position which will place door 26 between scoop member 12 andreceptacle 14.

Door 26 comprises a planar sheet of material, such as plastic. Thissheet of material is generally rectangular in shape so that door 26 iscomplementary to opening 20 defined in scoop 12. An upper end 26 a ofdoor 26 may be secured to frame 18 by a hinge as will be describedbelow. A lower end 26 b of door 26 is spaced a distance from upper end26 a and extends for a short distance below a bottom end of opening 20.In accordance with an aspect of the invention, the upper end 26 a ofdoor is of a first thickness “T1” (FIG. 4) and the lower end 26 b ofdoor is of a second thickness “T2”. The second thickness “T2” is greaterthan the first thickness “T1” so that door 26 tapers from lower end 26 btoward top end 26 a. This change in thickness causes door 26 to beslightly weighted at its lower end 26 b. The additional weight helpsensure that door 26 will move from an open position to a closed positionquickly and easily. The additional weight on lower end 26 b also aids inensuring that door 26 will completely close off opening 20.

Door 26 may, alternatively, be of a relatively constant thickness fromits top end 26 a to its bottom end 26 b. However, if door 26 is ofsubstantially the same thickness from top end 26 a to bottom end 26 bthereof, door 26 may not move to the completely closed position and maynot stay shut. Door 26 may also take longer to move from the openposition to the closed position. In order to address this issue, door 26may be weighted in another manner such as by securing one or moreweighted strips proximate bottom end 26 b. It is, however, cheaper andsimpler to taper the door 26 in the manner described above.

Door 26 may be secured to frame 18 by a hinge. The hinge may take anyone of a variety of forms. For example, the hinge may be a living hinge.Alternatively, as shown in FIGS. 4, 6, and 8, a pin 28 mounted betweenwalls 28 a on a top edge of door 26 may engage one or more protuberances29 extending outwardly from an interior surface of frame 18. Walls 28 amay also act as stops to limit travel of the door 26. Still further, asshown in FIG. 7, the hinge may also further include any type of spring,such as a torsion spring 30, which urges the door 26 into a closedposition. Whatever form the hinge takes, door 26 is able to move betweena closed position (FIG. 4) and an open position (FIG. 13).

When scoop assembly 10 is positioned at a scooping angle, i.e., wherescoop member 12 is correctly positioned to dig into litter material 46within litter box 48; or when scoop member 12 is generally horizontal(as in FIG. 4), the door 26 is in a closed position where it shuts offopening 20. In this position, door 26 is generally at right angles tofirst wall 14 a of receptacle. When the user is finished scooping petwaste out of litter box 48, they will turn receptacle 14 to a generallyvertical position (FIG. 13). This motion will cause door 26 to pivotabout an axis extending along pin 28 and move from a closed position toan open position. When door 26 is in the open position, opening 20permits access into the interior of receptacle 14. When scoop assembly10 is returned to a generally horizontal position, the door 26 willpivot about the axis extending through pin 28 and will return to theclosed position, shutting off access to opening 20 and therefore to theinterior of receptacle 14.

In the event the hinge is a spring-loaded hinge instead of one whichoperates under the force of gravity, door 26 will be urged by spring 30(FIG. 7) into the closed position. When scoop assembly 10 is moved to agenerally vertical orientation as shown in FIG. 13, the weight of theclumped pet waste 47 resting on door 26 will overcome the force appliedby spring 30, and door 26 will swing from the closed position to theopen position. As soon as waste 47 has dropped through opening 20, door26 will swing back to its closed position as spring 30 returns to itsoriginal position and/or length depending on the type of spring used.

Receptacle 14 is configured to receive and retain a replaceablecontainer 40 of disposable bags 44/44A therein. Bags 44/44A are retainedin the container 40 in much the same way as tissues are retained in atissue box. Container 40 is shown in FIG. 3 as being a rectangular cubein shape and includes an opening 40 a defined in one surface thereof.Although not identified herein, it will be understood that container 40defines an interior compartment in which a plurality of bags 44/44A isstored. When needed, bags 44/44A may be individually withdrawn from theinterior compartment through opening 40 a. When all the bags withincontainer 40 are used, container 40 may be disengaged from receptacle 14and thrown away. A new container 40 including a plurality of bagstherein will then be engaged with receptacle 14. Since container 40 isengageable with receptacle 14, a recessed region complementary to theexterior shape of container 40 is provided in receptacle 14. To thisend, receptacle 14 defines a first aperture 35 in first wall 14 a and asecond aperture 36 is defined in fifth wall 14 e. First aperture 35 maybe generally U-shaped when viewed from above and may be of a size andlocation that is at least slightly larger than opening 40 a of container40. Second aperture 36 is of a size and shape complementary to a side ofcontainer 40. Four walls 37 a, 37 b, 37 c, and 37 d are provided todefine and surround a compartment 37 that is accessible through each offirst and second aperture 35, 36. Compartment 37 is substantiallycomplementary is size and shape to container 40. First and secondapertures 35, 36 are in communication with compartment 37. Compartment37 is separated from cavity 32 and thus cavity 32 has only one openinginto the same, namely the opening defined by the lip 14 f formed byouter edges of walls 14 a, 14 b, 14 c, and 14 d. The opening ispositioned opposite fifth wall 14 e. It will be understood that whilecompartment 37 and container 40 are both illustrated and describedherein as being generally a rectangular cubic shape, any complementaryshaped compartment and container other than ones having a rectangularcubic shape may be provided in receptacle 14.

One or more opposed ridges 38 extend inwardly into compartment 37 fromfirst and second walls 37 a, 37 b. A pair of spaced apart ridges 38extends inwardly into compartment 37 from the interior surface of firstwall 14 a of receptacle. Additional ridges may be provided on third wall37 c if desired. Ridges 38 are provided so as to frictionally engage theexterior surface of container 40 and thereby frictionally retaincontainer 40 in compartment 37 when pet scoop assembly 10 is used. Whencontainer 40 is engaged in compartment 37 the receptacle 14 acts as acaddy and storage means for the bags 44 that are for later use withscoop assembly 10.

During use, a single bag 44 is withdrawn outwardly through opening 40 aof container 40 and out through first aperture 35 in first wall 14 a ofreceptacle 14. Scoop member 12 is disengaged from receptacle 14. Bag 44is positioned within cavity 32 of receptacle 14 and then scoop member 12is re-engaged with receptacle 14, trapping an upper edge of bag 44between outer edge of walls 18 a-18 d and lip 14 f. When bag 44 is sotrapped, bag is held in an open position where bag 44 is substantiallycomplementary to cavity 32 of receptacle 14. The withdrawal of bag 44from container 40 results in a second bag 44A which is located withinthe container to become positioned for subsequent withdrawal therefrom.In some instances, the withdrawal of bag 44 may cause part of the secondbag 44A to extend outwardly through opening 40 a and first aperture 35and thus be in a ready position for withdrawal from container 40. Inother instances, the user will simply insert their fingers throughopening 40 a and grasp the second bag 44A and withdraw the same fromcontainer 40.

It should further be noted that bottom wall sections 12 a′, 12 a, 12 bof scoop member 12 and second wall 14 b of receptacle 14 aresubstantially uninterrupted and free of barriers between them (apartfrom door 26) when receptacle 14 is engaged with scoop member 12. Thisensures that when pet waste 47 is received on the bottom wall sections12 a′, 12 a, 12 b of scoop member 12, the waste is able to readily andeasily slide from bottom wall sections 12 a′, 12 a, 12 b and onto aninterior surface of bag 44 resting on an interior surface of second wall14 b. The pet waste will not become hung up on little ledges or dropinto depressions that are provided between the scoop member andreceptacle as is the case in some prior art devices.

Scoop assembly 10 is used in the following manner. A bag 44 ispositioned so as to line cavity 32 within receptacle 14. This isaccomplished by withdrawing a bag, such as bags 44 or 44A (FIG. 1)through first aperture 35 in first wall 14 a Receptacle 14 is thendetached from scoop member 12 by depressing at least the first wall 14a, or the first and second walls 14 a, 14 b inwardly toward each otheras indicated in FIG. 14 by arrows “A”. This motion causes first wall 14a (and second wall 14 b) to flex inwardly and causes protrusions 34 toslide out of the associated apertures 22, thereby breaking theinterlocking engagement between scoop member 12 and receptacle 14.Receptacle 14 is then pulled away from scoop member 12 or vice versafrom the position shown in FIG. 1 to the position shown in FIG. 2.

Bag 44 is then opened up and positioned in cavity 32 in such a way thatthe upper edge of bag 44 is pulled outwardly over the rim 14 g (FIG. 2)of receptacle 14 and over ridge 15. Scoop member 12 is re-engaged withreceptacle 14 and protrusions 34 are slid, once again into apertures 22.Movement of the scoop member 12 is arrested by ridge 15. The engagementof scoop member 12 and ridge 15 traps the upper edge of bag 44 betweenwalls 18 a-18 d of scoop and lip 14 f of receptacle 14, thus keeping bag44 in an open position. Bag 44 thus effectively lines cavity 32.

The user then holds handle 16 and angles scoop member 12 in the mannershown in FIG. 10 such that rim 25 of second section 12 a of the bottomwall digs into litter material 46 as shown by the arrows. This causes aquantity of litter material 46 including pet waste 47 to slide ontotines 23 of third section 12 a′ of scoop member 12. The litter material46 and waste 47 slides down third section 12 a′ and onto the secondsection 12 a of scoop member 12. Scoop member 12 is then lightly shaken.This motion causes un-clumped litter material 46 to drop back intolitter box 48 through apertures 24 (FIG. 11). Clumped litter material47, which includes pet waste, remains on second section 12 a of scoopmember 12. Scoop assembly 10 is then moved from a generally horizontalorientation to a generally vertical orientation (see FIGS. 12 and 13).The clumped litter material 47 slides from second section 12 a onto thefirst section 12 b of the bottom wall, and toward opening 20. If door 26is secured to frame 18 by a living hinge or by pin 28, the movement ofthe scoop assembly 10 from a horizontal position to a vertical positionwill cause door 26 to begin to swing into an open position. As scoopassembly 10 is moved into the vertical position, clumped pet wastematerial 47 slides off first section 12 b, drops through opening 20 andinto bag 44.

Because door 26 opens through action of gravity, door 26 remains in theopen position until the orientation of scoop assembly 10 is changed. Ifdoor 26 is secured by a spring-loaded hinge 28/30 (FIG. 7) to frame 18,then the weight of clumped litter material 47 sliding onto door 26 willcause door 26 to open to a degree sufficient to allow clumped material47 to drop through opening 20 and into bag 44. Door 26 will then swingback to the closed position under force of the spring 30 returning toits at-rest position. If the user wishes to scoop additional clumpedmaterial 47 from litter box 48, they reorient scoop assembly 10 into ahorizontal position. If the door 26 closes through the action ofgravity, this movement from vertical to horizontal will cause door 26 toswing closed. Thus, door 26 is in the closed position when the nextscoop of litter material 46 is taken from litter box 48. The previouslyscooped clumped material 47 is therefore safely retained within bag 44and receptacle 14 by the closed door 26.

When the user is finished scooping clumped litter material 47 fromlitter box 48, receptacle 14 is disengaged from scoop member 12 in themanner previously described, the bag 44 is withdrawn from cavity 32, andthe top of the bag 44 is tied closed. Bag 44 is then pulled out ofcavity 32 and is thrown away. Alternatively, the entire receptacle 14may be tipped upside down so that bag 44 with clumped litter material 47slides out of cavity 32 and into the garbage. A new bag 44A is thenpulled out of opening 40 a in container 40 and that replacement bag 44Ais positioned in cavity 32 as previously described with reference to bag44. Receptacle 14 is engaged once again with scoop member 12 trappingthe bag 44A in the open position within cavity 32 so that the scoopassembly 10 is ready for its next use.

FIG. 16 shows a storage position for scoop assembly 10 where scoopmember 12 is detached from receptacle 14 and has been inverted andinserted into cavity 32. In order for this to be accomplished, scoopmember 12 has to be dimensioned in such a way that at least the frontregion of scoop member is insertable through the opening defined byupper end (lip 14 f) of receptacle 14. In particular, the distance “D1”(FIG. 2) between the outside surfaces of side walls 12 c and 12 d isless than the distance “D2” between the interior regions of the lip 14 fprovided at outer ends of side walls 14 c and 14 d of receptacle.Additionally, the distance “D3” between the lowermost region of bottomwall sections 12 a, 12 b and the uppermost edges of side walls 12 c, 12d is less than the distance “D4” between the interior surfaces of thelip 14 f on first wall 14 a and second wall 14 b of receptacle. Whenfront region of scoop member 12 is inserted into cavity 32, most or allof frame 18 and all of handle 16 do not pass through the opening tocavity 32. This ensures that the user will be able to grasp handle 16and, by manipulating handle 16, re-engage scoop member 12 and receptacle14 without touching the front region of scoop member. Inverting scoopmember 12 as illustrated in FIG. 16 and inserting the front regionthereof into cavity 32, ensures that the possibility for contaminatingother surfaces in the home with the front region is greatly diminished.

Receptacle 14 may be stored in an upright orientation by placing feet 13on fifth wall 14 e in contact with a flat surface. While scoop member 12may be left engaged with receptacle 14 and then receptacle be placedfeet 13 first on the flat surface for storage, it is preferable todisengage scoop member 12 from receptacle and then store the scoopassembly 10 in the position shown in FIG. 16. Receptacle 14 holds andretains scoop member 12 off the floor in either orientation i.e., withreceptacle 14 standing on its feet 13 on the ground or when scoop member12 received in cavity 32.

FIG. 17 shows an alternative version of a scoop assembly, generallyindicated at 110. Scoop assembly 110 is configured to be most useful forpicking up pet waste resting on a surface such as grass. Scoop assembly110 includes a receptacle 114 that may be substantially identical instructure and function to receptacle 14. Receptacle 114 may be largerthan receptacle 14. Scoop assembly 110 may include a modified scoopmember 112 that is detachably engageable with receptacle 114 in much thesame manner as scoop member 12 engages receptacle 14.

Scoop assembly 110 may differ from scoop assembly 10 in that instead ofa container 40 of bags 44 engaged in a recessed region or compartment 37in receptacle 14, a roll of bags (not shown), such as bag 44 b may bestorable within the interior cavity of the receptacle or within aseparate compartment provided therein. A hole 135 is defined in the wall114 a of receptacle. A single bag 44 b is withdrawn from the roll ofbags through hole 135, is opened up and is secured within a cavitydefined in receptacle 114 in substantially the same manner as describedwith reference to scoop assembly 10, bag 44 and receptacle 14.

Scoop member 112 may include a plurality of tines 150 which extendoutwardly and forwardly from a frame 118. Frame 118 includes a firstwall 118 a, a second wall 118 b, a third wall 118 c, and a fourth wall118 d, and a fifth wall 118 e which bound and defines an opening 120.Tines 150 extend forwardly from second wall 118 b and are spaced apartand separated from each other by apertures 152. Tines 150 may begenerally triangular in cross-section and are oriented such that theapex of the triangular shape is presented as part of the upper surfaceof the bottom wall of scoop member 112. The upper surface of the bottomwall is that surface upon which pet waste will rest. This shape of tine150 is advantageous because it presents the least surface area that willcontact any pet waste when the scoop assembly 110 is used. The shapealso makes it easier for the tines 150 to pass through grass. However,any other desired and suitable configuration of tine may be used. Aregion of each tine 150 adjacent frame 118 is angled in much the samemanner as first section 12 b of scoop assembly 10. The rest of the eachtine 150 is substantially parallel to a second wall 114 b of receptacle114. Scoop member 112 further includes side walls 112 a, 112 b whichextend outwardly and forwardly from frame 118. Side walls 112 a, 112 bextend upwardly and outwardly from the bottom wall comprised of tines150. Side walls 112 a, 112 b are shown free of apertures but it will beunderstood that they may include apertures therein.

A door 126 is connected by a hinge (not shown) to first wall 118 a offrame 118. This hinge is substantially identical in structure andfunction to any of the hinges described with reference to door 26 andframe 18. Door 126 functions in substantially the same manner as door26.

An elongate handle 154 may be engaged with first wall 118 a. Handle 154may be in the form of a broom-handle type of pole that is threadablyengaged in an aperture 156 of a mounting member 148 provided on frame118. Any other method of securing the pole type handle may also beutilized. Handle 154 may be of a length that is sufficient that the userwill not need to bend over to perform the scooping action in order tolift pet waste off a surface such as grass.

Scoop assembly 110 is used by placing a bag, such as bag 44 b inreceptacle 114 and then engaging a top edge of that bag between scoopmember 112 and receptacle 114 as has been previously described withreference to receptacle 14 and scoop member 12. While grasping handle154 and standing upright, the user will pass tines 150 through the grassand under a clump of pet waste. The spaces 152 between tines 150 permitgrass to flow therethrough and substantially prevent scoop member 112from becoming snagged in the grass. The pet waste will slide onto theupper surfaces of tines 150. The user is then able to change the angleof scoop member 112 so that door 126 is caused to move to the openposition. This allows the scooped pet waste to slide down the angledback region 150 a of tines 150, through opening 120 and into the bag inreceptacle 114. When scoop assembly 110 is returned to its operationalposition (shown in FIG. 17), door 126 will return to the closed positionunder force of gravity. (If door 126 is secured by a spring-loadedhinge, then door 126 will be pushed open by the pet waste and then moveback to the closed position.)

When the user is finished picking up pet waste, scoop member 112 isdetached from receptacle 114 and the bag 44 with the gathered pet wastetherein is disposed of in the manner previously described herein withreference to pet waste scoop assembly 10.

Both the scoop member 12, 112 and the receptacle 14, 114 may befabricated from a suitably rigid and durable plastic material. This typeof material is readily and easily cleaned using water containing asuitable detergent. It will be understood that any other suitablematerial may be used to fabricate scoop member 12, 112 and receptacle114.

It will be understood that variations of the above-described pet scoopassembly are possible. For instance, different types of latchingmechanisms other than protrusions 34 and apertures 22 may be employed tokeep scoop member 12, 112 and receptacle 14, 114 engaged together.Various patterns and placements of apertures 24, 152 in scoop members12, 112 may be employed and the cross-sectional configuration of tines23, 150 may be changed. Other ways of mounting the roll of bags (notshown) in the receptacle, including mounting the same on a rod situatedwithin cavity 32 or within compartment 37, are possible.

Scoop assembly 10, 110 may also be used without engaging a disposablebag 44 therein—the user will simply gather the pet waste in the cavity32 of receptacle 14, 114 and then tip the gathered pet waste directlyfrom the cavity 32 and into the garbage. Receptacle 14, 114 may beprovided with ventilation holes or may be provided with another means ofsecuring a bag 44 therein other than trapping the upper edge of the bagbetween the scoop member 12, 112 and the receptacle 14, 114.

It will further be understood that instead of the door hinge beingpositioned adjacent a top edge of door 26, 126; the hinge may bepositioned along one or the other of the side edges of the door or evenalong the bottom edge of the door. In the two latter instances aspring-loaded hinge is preferable as moving the assembly 10, 110 betweena horizontal position and a vertical position would not necessarilycause the door 26 to swing open or closed under force of gravity.

In one aspect, the invention may provide a method of removing pet waste47 from a litter box 48 comprising providing a scoop assembly 10 havinga scoop member 12; a receptacle 14 detachably engageable with scoopmember 12; and a door 26 disposed intermediate scoop member 12 andreceptacle 14, said door 26 being movable between an open and closedposition; detaching scoop member 12 from receptacle 14; inserting adisposable bag 44 through an opening defined by an outer end of lip 14 fof receptacle 14 and into a cavity 32 defined in receptacle 14; foldingan upper end of bag 44 over the outer end of lip 14 f of receptacle 14;re-engaging scoop member 12 with receptacle 14; and trapping bag 44between scoop member 12 and receptacle 14 in an open position (as shownin FIG. 1).

It should be noted that because bag 44 is trapped in this manner, thebag 44 is always held in an open position and cannot be closed unlessand until scoop member 12 is detached from receptacle 14. This ensuresthat any pet waste 47 captured during a scooping action will always beable to slide readily and easily into the interior of the bag andwithout contacting any part of the receptacle 14.

When scoop assembly 10 is in the position shown in FIG. 1, the assemblyis ready for use to remove pet waste 47 from a litter box 48 asillustrated in FIGS. 10-16. Consequently, the method further includesinserting a front end (i.e., third sections 12 a′) of scoop member 12into pet litter 46 in litter box 48 (FIGS. 10 and 11); rotating thescoop assembly 10 from a horizontal orientation toward a verticalorientation (FIG. 12); pivoting door 26 to the open position as scoopassembly 10 is rotated; and sliding captured pet waste 47 down the scoopmember 12 and into the held-open bag 44. It should be noted that thescoop assembly 10 most desirably used to scoop pet waste 47 from thelitter box 48 and then moved to a vertical orientation while scoopassembly 10 is positioned over the box 48. This positioning will ensurethat any unclumped pet litter 46 will drop back into box 48 so that theuser does not create a mess in the areas surrounding box 48.

The method may further include rotating scoop member 12 from thevertical orientation back toward the horizontal orientation; rotatingdoor 26 to the closed position to trap captured pet waste 47 in bag 44within receptacle 14; and repeating the steps of inserting front end(i.e., third section 12 a′) of scoop member 12 into pet litter 46;rotating scoop assembly 10 from the horizontal orientation to thevertical orientation, pivoting door 26 to the open position, and slidingthe captured pet waste 47 into the open bag 44.

The method may further include the steps of disengaging scoop member 12from receptacle 14; withdrawing bag 44 with captured pet waste 47 fromthe cavity 32 (FIGS. 14 and 15); and disposing of the withdrawn bag 44in the trash.

The method may further include the steps of withdrawing a new bag 44Afrom a disposable container 40 retained in a compartment 37 provided onreceptacle 14; inserting the new bag 44A into cavity 32 in receptacle14; folding an upper end of the new bag 44A over outer end of lip 14 fof receptacle 14; engaging scoop member 12 with receptacle 14; andtrapping the new bag 44A in the open position between scoop member 12and receptacle 14.

It will be understood that receptacle 14 may be used without the bag 44.In other words, pet waste 47 may be collected directly into the cavity32 of receptacle 14. Thus, the same method of use set out above, absentthe limitations regarding the insertion, clamping engagement and removalof the bag 44, can be practiced with the scoop assembly 10.

In the foregoing description, certain terms have been used for brevity,clearness, and understanding. No unnecessary limitations are to beimplied therefrom beyond the requirement of the prior art because suchterms are used for descriptive purposes and are intended to be broadlyconstrued.
